Method and system of increasing wear resistance of a part of a rotating mechanism exposed to fluid flow therethrough

A part of a rotating mechanism having increased wear resistance to fluid flow associated with the rotating mechanism comprising:

• a portion configured to be exposed to wear during the fluid flow associated with the rotating mechanism, the portion being manufactured to have a dimension different from that of a final dimension thereof by a thickness of a protective coating to be applied thereon, and the portion comprising:
• a protective coating of an aluminum bronze alloy melted on the portion having the different dimension through welding deposition, the aluminum bronze alloy having a chemical composition of 6-10% aluminum 9.5-18% of a plurality of metals including manganese, iron and nickel, with copper constituting a remaining chemical composition thereof, the welding being one of:
• Metal Inert Gas welding and Metal Active Gas welding, and the melted protective coating being mechanically treated after the welding deposition, and
• at least one layer of solid-alloy applied over the mechanically treated melted protective coating through an electro-erosion deposition process, the electro-erosion involving:
• maintaining a micro-solidness of the at least one layer of solid-alloy by constraining the percentage of cobalt between 6-12%,
• minimizing a fragility of the at least one layer of solid-alloy by constraining the percentage of cobalt between 6-12%,
• utilization of an electrode made of the solid alloy having a chemical composition of 6-12% cobalt and 88-94% carbides of a plurality of metals including tungsten carbide, chromium carbide and vanadium carbide, and
• transfer of particles of the solid alloy onto the mechanically treated melted protective coating in accordance with the utilization of the electrode,
• wherein the mechanical treatment of at least one of the melted protective coating and the at least one layer of the solid-alloy is continued after the solid-alloy deposition to obtain the final dimension of the portion.
